“Okay, biology twitter, what the heck is this?? Found on a beach in Texas City, TX,” the post reads.

The finned, fanged, eyeless creature is oblong in shape, with mottled skin and a long tail.

The photos have drawn comparisons on social media to the monstrous star of 1979 science-fiction horror film Alien.

Some Twitter users have suggested the creature might be some kind of eel – a claim supported by Smithsonian National Museum of Natural History eel specialist Dr Kenneth Tighe, Earth Touch news reports.

Dr Tighe has identified it the corpse as belonging to an Aplatophis chauliodus, also known as a “snake eel”.
